3 SHEETS-SHED 3.

(SKT sie means of tbe pump. 3l designates s clutch member whose upper end 32 is to tbe rotor in any suitible manner srcli the bolts 3? and nuts The lower of the clutch member carries the internal gear 36 by ineens of tbc 'screw 37 or sonic suitable similar connection.

Mesbing with the internal geen: teeth the' internal geur 8G are the pinion 3? wbicli erecurriedon tbe pinion sbatte 3S? and fastened thereto by ineens of tbe kevs lil).

lieshiiig with the opposite side of tbe pinion gear 37 from the internal geen 36 is an external gear il having' an inner beveled Yluce 4t2 and its lower end i3 in engagement with the bull thrust bearing As clearly appears in' Figure i of tbc drawings s nut 45, which l term tbe moin power nut, surrounds and enguges tbe power screw EZOfend hes its-upper end fit-3 in engagement with the tlnustv 'washer 27' und its lower end in engngernent'witli tbe roller thrust bearing Lili. ils clenrljv appears in the drawings, tne reversing incniber i? surrounds the renin power nut elo and lies bc-F tween it 'und tbc clutch member 3l. 4reversine member 47 is provided with oppositiely beveled faces i8 und 529 is vided with e circumferential. groove 50. A. slip voire 5l surrounds tbe reversing; cintcb member i7 und .has en extending; portion 52 which extends into tne circuinferentinl groove of 'bbc reversing clutcii member.

The arrangement olf the parte tbus de- Y scribed are such that there is en opening; 53

ill

between the clutch member 31 sind tne pin'n ion geur 37 and eiiternsl geur Lt. lt is iurtber to be noted that tbe clutch member 3i. has en inner beveled iuce 54 for engr-gement with the beveled fece l? of the reversing rlutclrmember, tbe more particular cooperation oi' which will be described luter.

lt will be further notedK tluit the bearing bushing: 23 carried in tbe lower surrounding yoke 17 supports the'roller thrust bearing i4 which in turn supports* tlie-n'inin power nut l5 and tlie external geer el.'

Screw tliresdedly sttucb-isil 55 by' some sin'iilsr menne, are tbe-lownwurdly y tendingl reversing rods wbicii pnss through the bottom closure l5 ot erasing 9 es et 57.. A spring' ball tension assembly 58 is carried by the bottom clnsure ii et u. point edjucent the passage, oi: tbe reversing rod s6 through this closure and the bel-i 59 ci' the assembly 58 is edupted to sent nltern nntely in the pockets G0 of tbe' reversing rods, as will hereafter be more billy described. 'v l At a point adjacent the 'c ttorn closure l5 of tbe' casing- 9 is u reversing; stop 6l. fastened to und carried by tbe reversing; rods y 56 by ineens of tbe screw boite wbile e point edgecent tbc top ot' the wel?,

o ed by the reversing rods 56 by ineens of screw bolts ffl. 'v

bottom of the casing `il) and the top of lthe 'lllie ends @7 of the clamp G5 extend con" our, from tbe pump rodli) es clears ly appears in the drawings, and is intendcd to :alternately strike the reversin stops 61' and 63 as the purnp' rod is raise and low# ered, as will hereafter be more particularly described. l

v The clamping 'construction 65 `willvbe duplicetcd at a point above the power .screw 20' to limit the 'downward movement of the pump -rod and to provide a lifting means for tbe pump rod :is the power screw 20 arisesy und' comes in contact with it. No further description of this element is considered necessary inasmuch eis it is n niereduplication. ci parts and construction wliicl'u has heretofore been describedv und is shown in Fis. l or the drawings.

llo compensate for tbe Wear between the beveled fecese and 49 of the reversing clutcii i7 end the beveled fece 42 of the externel ggeur il and the beveled falce 54 of' the clutch member 3 1 the beveled feces of the revcrsin; clutch member can be provided with a rrction lining attached by megs of counter-sunk screws, if desired.' l

Attention is directed to the fact that the power screw 20 lisis throughout vits length s keyfway 68 whiclrkey-wny engages' the keys 22 inv the bushings' 23 as the power screw il() is raised and lowered to prevent' it from rotating. lt will be also'noted that tne mein power nut 45 is provided with u ley 69 which fnstensit to insure rotation with the reversing clutch member 47, and tbe inner *fece of 47 is provided' with u key-way so tlint it willslidelo'n the key 159 of tbe mein power nut.

To insure rigidness of the support of the pump and its housing on the well tubing, I lieve provided e pluraiity of the supporting rods 7 whose upper ends are secured tlircugrliout 7G in the boss projections Il of tbe closure member 'l".

Before describing the operation of my device ll wish to state that riiy pumping heed be 'provided 'with no voltage release and n? under-load coil.A An external swit'li will" be provided for starting and. stopping the pumping heed. The under-load coil will nivo en automatic stop arrangement for the tubing-i ,is n cleinp beld in position f lie pump rod i9 by ineens of tbelboltsx reversing stop 68 fastened to and carstened to 'the pump rod 19 between the well when it is Pumped od.
